Description
The United Electric H100-171 Differential Pressure Switch Nexa-4X is used to close or open a single-pole, double-throw contact when the difference between the pressures reaches a predetermined set point, to allow the automated reaction of the HVAC systems. The inner sensing element detects a difference in pressure 1-20 PSI between two points and switches as a result. It entails the installation of the switch in the designated line or duct and hooking it to the control circuit. This element helps to monitor the correct pressure and helps to ensure the safe and stable work of HVAC systems.
